Date: Sun, 25 Dec 2016 13:30:24 +0530 From: Bhumika Goyal <bhumirks@...il.com> To: julia.lawall@...6.fr, wim@...ana.be, linux@...ck-us.net, linux-watchdog@...r.kernel.org, linux-kernel@...r.kernel.org Cc: keescook@...omium.org, Bhumika Goyal <bhumirks@...il.com> Subject: [PATCH] drivers: watchdog: pika_wdt: add __ro_after_init to ident The object ident of type watchdog_info structure is not modified after getting initialized by pikawdt_init. Apart from getting referenced in init it is also passed as an argument to the function copy_to_user but this argument is of type const void *. Therefore add __ro_after_init to its declaration.
